Those of you who've been around a while, and who live in the UK, might remember Earth Shaker. It was a Spectrum game given away one month on the Your Sinclair covertape. It's essentially a version of Boulderdash, with extras like jumping jelly beans, teleporters and barriers.

I decided to have a go at creating a DS port, mainly to test out my 2D graphics library (WoopsiGfx). There are a few features missing - sound effects and 24 of the levels - but it is perfectly playable in its current state.
